Hi
Thanks Furat
Please see the attched config file. I am looking at boot time info displayed on
the QEMU terminal, also I checked cpuinfo for cache sizes after boot. I compile
this file using
scons -Q c=16 config=config/yasir.conf
Regards
Yasir

How are you checking the cache configuration ?
Can you attach your configuration file ?
